Question about 1991 Saab 900

1 Answer

Auto transmission not working

I have recently bought a 91 saab 900 auto convertable
Auto transmission not working, unable to get into 2nd gear, tho will do this occasionally. Was working perfectly until when climbing a hill at low speed, I pushed accelerator to floor to drop back to first gear from 2nd, which it did OK. After this it did not go from 2-3 unless I stopped, put into neutral then put into drive, and then it worked fine, for 3-4 times. Since then getting from 1-2 is problematic, even when I move gear shift into 2.

    Thanks for that, Is this problem related to my dropping down a gear as explained? This service, is it a big job (ie, more than a day), or realistically am I wasting $ trying to fix it rather than hunt around for used part? Can had done 130,000 ks (100,000 miles or so) so theoretically should be fairly new tho previous owner had it garaged for periods.
    I have been driving newer automatics for a while, and have noticed on the saab that there is an increasing jolt when putting it into gear, drive or reverse. Are these transmissions more clunky than Subaru or hyundai ones?
    Also, see 'Iam thinking the valve body is not operating properly. Do a
    transmission service and while its open replace the valve body gasket
    abd ball checks'
    What do you mean by ball checks?

    Thanks for that. In a bizarre twist, just went for a drive and the transmission worked beautifully after an initially long period in 1st, no clunk, smooth, changing up at appropriate revs, no issue changing down. Like the last few days have been illusory!! Does that tell you anything?

  • markobrien Sep 28, 2009

    Thanks, and as an Aussie, I have to say thanks mate. Cause it works it cannot be structural, so reckon you are right. Will I need to go auto specialist for that, or local mechanic?

  • markobrien Nov 18, 2009

    Sorry it took me so long. had trans oil checked, clean as whistle, unknown what caused it as it has fixed itself. You must be very good mechanic as you only have to think about things and they fix themselves! Cheers and thanks again.

Iam thinking the valve body is not operating properly. Do a transmission service and while its open replace the valve body gasket abd ball checks. If this does not fix it have the bands adjusted.

    the shifting being clunky/hard is a sure sign of the valve body having some issues. The valve body has ball bearings in the grooves of the body. these balls move to block and allow the flow of ATF to change gears and shift the transmission. Yes its a big job, something a person can do. None the less a big one. It may be better to just have it done. It may cost 300-600.

    I feel that would solve your shifting issues. Anymore questions feel free to ask.

    Best of luck.

Had the same type of problems with my 95 Saab 900. A bushing in the shifter linkage kept popping out. Found out after lots of frustration there was a new shifter linkage mechanism out for 94 to 97 Saabs that fixed this problem. Not sure if it relates. I found the part here:

1989 saab automatic convert-able reviews. What is anyones experience with these automatic. 145km auto just replaced. looking to buy. simon

I used to have an automatic one of these. I would say that it is the best car i've ever driven. Two things to look out for though, first make sure that the static gear is ok, ie put it into park and make sure it doesn't roll -- this is common on these. Take for a test drive, these cars have 3 forward gears, make sure that it doesn't keep slipping from 2nd-3r, that will mean the transmission fluid is no good. Drive it fast on an open road, make sure the gearbox doesn't whine. Other than that, mine was great (until I crashed it) very sturdy and reliable for an old auto

Starter Relay???

There's no relay. Either the solenoid is bad or you need to have your starter rebuilt or replaced. For help with repairs and finding parts check out saabnet dot com You can remove the starter and have it tested for free at some auto parts stores. Look up auto electric in your yellow pages for alternator and starter rebuilding, and save up to 50% vs a rebuilt starter from the parts store.
